GOTCHA, a snappy acronym for the decidedly less snappy Generating panOptic Turing Tests to Tell Computers and Humans Apart, is aimed at stymying hackers from using computers to figure out passwords, which are all too often easy to guess. GOTCHA, like its ubiquitous cousin CAPTCHA, relies on visual cues that typically only a human can appreciate. The researchers don't think that computers can solve the puzzles and have issued a challenge to fellow security researchers to use artificial intelligence to try to do so. You can find the GOTCHA Challenge here."
